Wideband, variable-bandwidth distributed amplifier |
摘要 |
A variable bandwidth, distributed amplifier circuit includes an input transmission line; an output transmission line; and a plurality of amplifier cells having a respective plurality of cell inputs distributed along the input transmission line and cell outputs distributed along said output transmission line. Each amplifier cell comprises a cascode amplifier having an input transistor, an output transistor, and a variable impedance device in a circuit branch coupled to a gate of the output transistor. The impedance of the variable impedance device is responsive to a variable bias control signal.
